双馈风电机组次同步谐振分析与抑制策略
Analysis and Suppression Strategies on Sub-synchronous Resonance of DFIG
摘要
Abstract
The interaction between the controller of doubly-fed induction generato(r DFIG)and series compensated transmission system may induce sub-synchronous resonanc(e SSR)in wind farm. Two approaches to suppress SSR were proposed by deeply exploring the relationship between the controller of DFIG and SSR circuit. The first method is to take advantage of adaptive notch filte(r ANF)to mitigate the influence of SSR by cutting off SSR current feed into the controller;the second one relies on additional damping controller with band-pass filte(r BPF)in order to improve the damping of the system to suppress SSR. The theory and principle of these two methods was derived,followed by the detailed introduction of design methods. Eventually,the strategy combined the two methods of suppressing SSR was verified through simulation on Matlab,which provides a theoretical support for solving the SSR in wind farm.关键词
